When there is more than one address registered in the Profile System, there is a "null" request to the zip code service if you add a new address on "Invoice Address".

• Have more than 1 address registered in the Profile System;
• Select a pickup point;
• Click on "Deliver to another address" to add a new address on "Invoice Address" without selecting any other option.

The request was /api/checkout/pub/postal-code/null/postalcodenumber, so it returns the 500 error. Due to this return, it doesn't autocomplete the address using the zip code service.

Select an option already registered before adding a new address
